“I mean we never go out to dinner unless we go to somebody’s house. We never go to restaurants. That’s too extravagant. We invite people here. I cook. Well, if I’m giving a dinner party I get in help.”

Princess Michael, who lives with her husband at Kensington Palace, insists they are like normal people, using a pooper scooper when they walk their dogs and flying easyJet on trips to Biarritz. But she adds they fly club class for long haul flights.

She also describes herself as a hard worker, having previously written factual historical works, and now her first novel which is set to be part of a trilogy. The book is based on the life of the monarchy in 15th century France and follows the life of Yolande d’Aragon, who married Louis II, Duke d’Anjou, to become Queen of Naples, Sicily, Cyprus and Jerusalem.

She added: “I’m a workaholic. I’m a Capricorn, It’s my nature, And I’m convent educated: I sew better than any nanny we’ve ever had. And my father had a farm in Africa. Have you ever taken the insides out of a stag?”

The Princess, who was once referred to as “too grand for us” by the Queen says she thinks good breeding and a good character are equally important.

Among her loves include Michael Gove, who she describes as “a wonderful man” and “I love him.”

And she admits to having had Botox and a special French procedure called mesotherapie, which involves having your skin pricked with needles.
